This study is about developing a computer program to check blood flow in arteries using CT scans (special X-ray pictures). Invasive surgeries, like big belly surgeries for cancer, can be risky because they might hurt important blood vessels. Right now, doctors use a procedure called percutaneous angiography to check blood flow before surgery. This method is invasive, involving anesthesia (medicine to make you sleep), hospital stay, and high radiation exposure. This study aims to create a safer method using CT scans without the need for invasive procedures.

Key Points:

• This study focuses on people having pancreaticoduodenectomy (a type of surgery).
• Participants must be 18 years or older with good quality CT scans.
• There is no mention of compensation, but the study helps improve surgery safety by reducing risks.

If you qualify and decide to join, you will help create a non-invasive tool to predict changes in blood flow during surgeries, making them safer.
